Oil and gas operators assess the impacts, risks and benefits of different decommissioning options for infrastructure that has reached "end-of-life". This thesis aims to understand how fish and fisheries interact with subsea pipelines on the North West Shelf of Western Australia. Fish were in higher abundance around pipelines compared to areas without pipelines. Commercial trap fishers target pipeline infrastructure and demonstrate "rotational self-governance", taking advantage of a higher abundance of valuable fish species on pipelines than in surrounding areas particularly in water depth >80m. These results inform decommissioning approaches and provide knowledge of the impact of infrastructure in our oceans.
